Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Evertz SDVN 3080ipx-10G is a High Bandwidth Ethernet Switching Fabric for Video Application. This device exposes a web management interface on port 80. This web management interface can be used by administrators to control product features, setup network switching, and register license among other features. The application has been developed in PHP with the webEASY SDK, also named ‘ewb’ by Evertz. This web interface has two endpoints that are vulnerable to arbitrary command injection (CVE-2025-4009, CVE-2025-10364) and the authentication mechanism has a flaw leading to authentication bypass (CVE-2025-10365). CVE-2025-4009 covers the command injection in feature-transfer-import.php CVE-2025-10364 covers the command injection in feature-transfer-export.php Remote unauthenticated attackers can gain arbitrary command execution with elevated privileges ( root ) on affected devices. This level of access could lead to serious business impact such as the interruption of media streaming, modification of media being streamed, alteration of closed captions being generated, among others.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Evertz SDVN 3080ipx-10G is a video application ethernet switching fabric with a PHP-based web management interface (webEASY/ewb) on port 80. Two endpoints (feature-transfer-import.php and feature-transfer-export.php) contain arbitrary command injection vulnerabilities. Combined with an authentication bypass flaw (CVE-2025-10365), remote unauthenticated attackers can achieve root-level command execution on affected devices.

MitigationApply vendor-supplied patches from Evertz for CVE-2025-4009/10364/10365 when available. If patches are unavailable, immediately restrict network access to the management interface via firewall rules or network isolation, and monitor for indicators of compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device's web management interface or check the device label/documentation for the model number. Look for 'SDVN 3080ipx-10G' or 'Evertz' branding.
    Affected if The device is not an Evertz SDVN 3080ipx-10G (different models are not affected by this specific CVE)
  2. Confirm the web management interface is enabled
    Attempt to access the device's web interface on port 80 (HTTP). If a login page or web application loads, the interface is enabled.
    Affected if The web management interface is accessible on port 80 and responds with the webEVERY SDK ('ewb') application
  3. Check for the vulnerable endpoint
    Navigate to or probe for the presence of 'feature-transfer-import.php' in the /ewb/ or web interface paths. For example: http://<device-ip>/ewb/feature-transfer-import.php
    Affected if The file feature-transfer-import.php exists and is accessible on the web server
  4. Compare installed firmware version
    Check the device's firmware version through the web interface (typically in System Settings, About, or Status pages) or via CLI if available.
    Affected if The installed firmware version matches the affected version range for CVE-2025-4009 (no specific versions provided; contact Evertz to confirm if your version is vulnerable)
  5. Verify the similar endpoint exposure
    Also check for 'feature-transfer-export.php' endpoint which was affected by the related CVE-2025-10364.
    Affected if Either feature-transfer-import.php or feature-transfer-export.php is exposed without authentication

The environment is affected if the device is an Evertz SDVN 3080ipx-10G with an accessible web management interface that exposes the feature-transfer-import.php endpoint.
